Charcoal briquette machine is mainly used for pressing all kinds of powdery and waste materials including charcoal dust, carbon dust, bamboo charcoal powder, coke powder, hookah dust, graphite powder, date wood carbon and semi coke powder. Here Henan Fote Heavy Machinery Co., Ltd. (Company-Fote Ball Press Machinery) introduces the general solutions of charcoal briquetting press machine:
1. Briquettes have surface cracks
If the raw material contains too much moisture, the briquettes will have transverse crack; while if the moisture is too low, briquettes may have longitudinal crack. Besides, if the heating temperature inside the charcoal briquetting machine (Charcoal Briquetting Machine,Carbon Powder Briquetting Machine,Powdered Carbon Briquetting Machine - Fote Machinery) is too high, raw material will be over softened, and leads to insufficient feeding. Such circumstance also causes cracks to briquettes. Generally to deal with the insufficient feeding, usually the screw diameter shall be increased, or polish the screw surface and increase the span between screws.

2. The briquetting machine does not form briquettes
The heating temperature is too high or too low; severe abrasion of molding sleeve; the angle of pusher is not right; or raw material contains too much water. If the briquetting machine works normally, the briquettes are evenly extruded from the molding sleeve, and the color is brown with smooth surface and no cracks.
3. The “bang” inside charcoal briquetting machine
It may be caused by improper temperature control, raw material contains too much moisture, abrasion of pusher, misalignment of pivot, blockage of exhaust vent, too big or too small pusher head screw, or the sleeve is badly worn. So when there is blowout inside the machine, check the above causes.
4. The middle of briquettes has low density or scattered sawdust
This is because the pivot of the pusher is worn. The solution is to repair welding and thicken it. In addition, if the pivot is not straight, it will also cause such problem. Under such circumstance, the pivot shall be adjusted under high temperature.
5. The discharging outlet spurts air
This is because the feeding material is not enough, or raw material contains too much moisture, or heating temperature is insufficient.
6. The fracture surface of briquettes have shining surface, good density but bad hardness
This is because the head screw is too steep. You can make it smooth by polishing.
7. The briquettes bends
The raw material contains too much water.
